Abstract: In anti-dandruff hair care, sensory cues often are second to deposition/performance. Apparently, however, P&G inventors have a soft spot for both, as this patent for improving the feel of anti-dandruff conditioners demonstrates.

In anti-dandruff hair care, sensory cues often are second to deposition/performance. Apparently, however, P&G inventors have a soft spot for both, as this patent for improving the feel of anti-dandruff conditioners demonstrates.

The disclosed composition includes: a) a specified cationic guar polymer; b) a specific cationic copolymer; c) an anti-dandruff active; d) a cosmetically acceptable carrier; and e) a surfactant. The weight ratio of a:b is from ~1,000:1 to ~3.5:1; and the sum of a+b ranges from ~0.0001% to 0.7% w/w.

This composition forms coacervate particles upon dilution with water that have a squeeze flow viscosity from ~1 Pa•s to 100 Pa•s. Further, the percentage of coacervate particles with a floc size > 20 microns is from ~1% to 60%. The on-scalp deposition of the anti-dandruff active is minimally ~1 microgram/cm2.
